Boston center Perkins leaves Game 4 with shoulder injury

LOS ANGELES -- Boston Celtics center Kendrick Perkins left Thursday night's Game 4 of the NBA Finals against the Los Angeles Lakers in the third quarter with a left shoulder strain.

Perkins left the game with 9:35 left in the third after banging into Lakers forward Lamar Odom in the lane. Perkins walked off clutching his shoulder and was escorted to the locker room.

Perkins returned to the bench, and the team said he may return.

Perkins had two points and one rebound in 13 minutes, playing much of the game in foul trouble.
